Outstanding!  Amazing  river, amazing fish.  I went there a few years back with a buddy, absolutely the trip of a lifetime; want to go back for more.  But we had a guide and a jetboat; catching fish like that on a strictly DIY basis, from shore, puts guided fishing to shame.  Nobody handing you a rod that has a monster fish already  hooked...you get the fantastic satisfaction of knowing that you did it all yourself.  Bravo!
Question:  do you ever try using circle hooks for these fish?  I've only gotten into them for big channel cats in the past couple years, and today I can't imagine fishing natural bait of any kind without them.  They seem like they'd be ideal for this type of fishing?
